Two championships. Three straight NBA Finals. The Golden State Warriors' incredible dominance has been the overlying story line of the NBA for the past three seasons. But due to injuries, they enter the postseason hobbled and scuffling.

Enter Houston, the Warriors' most serious challenger in years. Led by MVP frontrunner James Harden and future Hall of Famer Chris Paul, their offensive style has terrorized defenses this season. Who knows what awaits if they meet in the Western Conference Finals?

In the East, LeBron James' Cleveland Cavaliers may face his most difficult path to the Finals yet. He's on a mission for his eighth consecutive Finals appearance, but he'll do it with a team that was overhauled just two months ago. Could it be the year that Toronto turns regular season dominance into its first Finals appearance ever?
